Mheni Kusungwa chinhu chakakosha kuchengetedza mumagetsi emagetsi system, ayo anoshandiswa kufungidzira iwo makuru magetsi emagetsi achipesana neOver-Voltage. Zinc oxide Arresters inotora zinc oxide varistors ine yakanaka volt-ampere hunhu husingaite sechinhu chayo chemberi, icho chinoratidza kushomeka kwakanyanya kana system yakasarudzika kubheta, iyo yazvino inongova nema microamp level; kana pamusoro pemagetsi, iyo yazvino iyo kuburikidza ne zinc oxide varistors inomhanya kumusoro, inogona kukurumidza kuburitsa simba reakawandisa-magetsi, nekudaro kudzikisira huwandu hwemagetsi, panguva iyi, zinc oxide varistor zvakare ine izvi maficha ehukuru kuyerera kugona, nekukurumidza kupindura kumhanya, kumhanya kupindura kumhanya, kuita kwakanaka kwekudzivirira uye zvichingodaro. MOAS yeiyi akagadzirirwa kutumira kunze.Iyo perfomance yevasungwa inosangana nezvinodiwa zve Standard IEC60099-4.
